iommu/amd: Fix panic accessing amd_iommu_enable_faulting
This fixes a bug introduced by commit d74169ceb0d2 ("iommu/vt-d: Allocate
DMAR fault interrupts locally"). The panic happens when
amd_iommu_enable_faulting is called from CPUHP_AP_ONLINE_DYN context.
Fixes: d74169ceb0d2 ("iommu/vt-d: Allocate DMAR fault interrupts locally")
